Slightly off topic, the climber and author Jon Krakauer, “Into Thin Air”, in another of his books describes the sight of a glacier when he briefly took his silvered sunglasses off to see what it really looked like in direct sunlight: “Ka-wow”.

This very scene occurs later in the fictional series Red Mars, Green Mars, Blue Mars, by the Robinsons. One of the characters takes off sunglasses on a glacier and says that.
